1) Financial Performance Overview
- O'Reilly Automotive reported a 5.6% increase in comparable store sales for Q4 2025, leading to a full-year comp of 4.7%, which was at the high end of their revised guidance of 4% to 5%.
- Total sales for 2025 reached $17.8 billion, reflecting a 6.4% increase year-over-year and over 50% growth in total sales volume since 2020.
- Operating profit for the year was $3.5 billion, a 6.4% increase from 2024, with an operating profit margin of 19.5%.

2) Segment Performance and Trends
- The professional segment drove growth with a 10% increase in comparable store sales for the second consecutive quarter, while the DIY segment saw low single-digit growth.
- Average ticket growth was in the mid-single digits, driven by 6% same-SKU inflation, although there were pressures from product mix composition.
- The company noted stabilization in DIY transactions, with some modest improvements month-to-month, but still faced slight negative traffic comps in discretionary categories.

3) Challenges and Cost Pressures
- O'Reilly faced significant cost pressures in 2025, particularly from rising healthcare and self-insurance expenses, which dampened overall performance.
- SG&A expenses as a percentage of sales were 33.0% in Q4, down from the previous year, but elevated costs in self-insurance and healthcare continued to be a concern.
- The company anticipates SG&A per store growth of 3% to 4% in 2026, with potential pressures from ongoing inflation in these areas.

4) Operational and Strategic Initiatives
- O'Reilly plans to invest $1.3 billion to $1.4 billion in capital expenditures for 2026, focusing on new store openings (targeting 225 to 235 new stores) and enhancing distribution capabilities.
- The company opened a new distribution center in Stafford, Virginia, which will support growth in the Mid-Atlantic and Northeast markets.
- O'Reilly expects to maintain a strong gross margin of 51.5% to 52% in 2026, driven by effective cost management and the continued evolution of its business model in Mexico.

5) Guidance and Outlook
- For 2026, O'Reilly established a comparable store sales guidance range of 3% to 5% and expects total revenues between $18.7 billion and $19 billion.
- EPS guidance for 2026 is set at $3.10 to $3.20, reflecting a 6.1% increase at the midpoint compared to 2025.
- The company remains cautiously optimistic about consumer behavior, particularly in light of potential tax refunds and seasonal weather impacts.

Bottom line: O'Reilly Automotive demonstrated strong financial performance in 2025, driven by robust sales growth and effective cost management, despite facing significant cost pressures. The company is strategically positioned for continued growth in 2026, with a focus on expanding its store network and enhancing operational efficiencies, making it a compelling investment for shareholders.
